Face Unlock on the vivo X300 Pro is designed to unlock your phone instantly with just a glance. When it stops working, you may notice that the phone fails to recognize your face, takes too long to unlock, or does nothing at all when you look at the screen. In most cases, this happens because of camera obstructions, incorrect settings, or temporary software glitches. The solutions below will help restore Face Unlock so your phone can recognize you again quickly.
Why Face Unlock Is Not Working on the vivo X300 Pro
- The front camera lens is dirty or blocked.
- Face Unlock is turned off or not properly set up.
- Poor lighting prevents the camera from recognizing your face.
- Recent system glitches affecting biometric features.
- Your stored facial data may no longer match your current appearance.
Make Sure Face Unlock Is Enabled
Face Unlock will not work if the feature is turned off in your security settings. Sometimes system updates or security changes can disable it without you noticing.
Open Settings, and then tap Fingerprint, face and password.
Tap Face, and then make sure Face Unlock is enabled.
Re Scan Your Face
Facial recognition may fail if the stored scan no longer matches your appearance. This can happen after lighting changes, wearing glasses, or after the phone struggles to detect your face multiple times.
Open Settings, and then tap Fingerprint, face and password.
Tap Face, and then select Add face to register your face again.
Clean the Front Camera
The front camera is responsible for scanning your face. If the lens is covered with dust, fingerprints, or dirt, the phone may fail to recognize you.
Locate the front camera, and then wipe it gently using a clean microfiber cloth.
Lock the screen, and then try unlocking the phone again.
Improve Lighting Conditions
Face Unlock relies heavily on proper lighting to capture facial details. If the environment is too dark, the phone may struggle to identify you.
Move to a brighter area, and then wake the phone screen.
Look directly at the camera, and then wait for the phone to unlock.
Restart the Phone
Temporary software glitches can affect biometric features like Face Unlock. Restarting the device refreshes system services and can restore normal functionality.
Press and hold the Power key, and then tap Restart.
Wait for the phone to boot up, and then test Face Unlock again.
Update the System Software
System updates often include fixes for biometric recognition problems. Installing the latest update can improve Face Unlock accuracy and performance.
Open Settings, and then tap System update.
Tap Check for updates, and then install any available update.
Face Unlock on the vivo X300 Pro is normally very reliable, but it can stop working when settings change or when the camera cannot clearly detect your face. After checking the settings, refreshing the facial scan, and updating the system, the feature should start working smoothly again.

Yes, but it depends on how the face was originally scanned. If you usually wear glasses, it is best to register your face while wearing them.
